A basketball player is balancing a spinning basketball on the tip of his finger. The angular velocity of the ball slows down from 18.5 to 14.1 rad/s. During the slow-down, the angular displacement is 85.1 rad. Determine the time it takes for the ball to slow down.

A heavy truck and a light car travel at the same velocity side-by-side on the highway. Both drivers apply the same braking force at the same moment. What will happen to the two vehicles?

a) The car will slow down more quickly than the truck.

b) The truck will slow down more quickly than the car.

c) Both vehicles will slow down at the same rate.

d) The car will slow down but the truck will continue at the same speed.

The blades in a blender rotate at a rate of $7500$ rpm. When the motor is turned off during operation, the blades slow to rest in $3.0$ s. What is the angular acceleration as the blades slow down?

To slow down a reaction, you can (increase/decrease) the concentration of the reactants.

Factor completely. $2 x ^ { 2 } + 9 x y + 7 y ^ { 2 }$

A coil of heavy open chain is used to reduce the stopping distance of a sled that has a mass $M$ and travels at a speed of $v_0$. Determine the required mass per unit length of the chain needed to slow down the sled to $(1 / 2) v_0$ within a distance $x=s$ if the sled is hooked to the chain at $x=0$. Neglect friction between the chain and the ground.

You are told that a basketball player spins the ball with an angular acceleration of 100 rad/s$^2$. (a) What is the ball's final angular velocity if the ball starts from rest and the acceleration lasts 2.00 s? (b) What is unreasonable about the result? (c) Which premises are unreasonable or inconsistent?

A pulsar is a rapidly rotating neutron star that continuously emits a beam of radio waves in a searchlight manner. Each time the pulsar makes one revolution, the rotating beam sweeps across the earth, and the earth receives a pulse of radio waves. For one particular pulsar, the time between two successive pulses is 0.033 s. Determine the average angular speed (in rad/s) of this pulsar.

In an inertial coordinate system, if the sum of the forces on a particle is not equal to zero, the particle is

(a) moving with a constant velocity opposite to the direction of the resultant force

(b) accelerating in the same direction as the resultant force

(c) moving with constant velocity in the direction of the resultant force

(d) accelerating in the opposite direction as the resultant force

A. in the same direction as the magnetic field lines B. in the opposite direction from the magnetic field lines C. at right angles to the magnetic field lines D. clockwise around the magnetic field lines

Which of the following statements about an array of arrays is true?

A. Both indexes in an array of arrays must be integer indexes.

B. An associative array can't be used as an array within another array.

C. All of the arrays within an array must have the same number of elements.

D. You can use both for loops and foreach loops to work with an array of arrays.

What action should you take if you arrive at an intersection before a vehicle on your left arrives?

A quarterback throws a Hail Mary pass with a vertical velocity of $64$ ft/s and a horizontal velocity of $45$ ft/s. Will the pass reach the back1 of the end zone $180$ ft ($60$ yd) away within $3.00$ ft of the height from which it was thrown?
